To all whom it may COl'tL'U/Tt.

Be it known that 1. .imcxiixonn Linn, a citizen of the United States.and a reaident of St. Paul, in the county ol' llaniney and State oflllinnesota, llaiu invented a new and Improved Plane, of which thelollrm'ing is a full, clear, and exact description.

This invention relates to planes, and more particularly to that class ofplanes known as router planes.

.n object of the invention is to provide a simple, strong and rllirientplane for rolling grooves or rectangular entities and ha ing means foreasily and rapidly adjusting the cutter.

A further Ulljtl'l ol the im-finliou h; to pro ride a device ol he via;tlrneribeil having handles by niean ol' winch it can be unionall) o];)(-,raled, and having a cutter :ulapieil to iJG-PlOjCtftEll from thephnuaim-h, winof said handlca eontiwflliirg the rottwai'n'l S'fl'V ingboth to operate the plane and to adjust the cutter.

V

Before ptUtLl'ftlllifl to a m re detailed explanation of my invention.it should be ande-rstood that the plane ran be natal tor the.

usual pronines to which a router plane is upplioahle, for inntance, theeotting away of nuitorial between saw cuts to form a groove, or theforming of rectangular cavities in wood and the like; for this purpose Iprovide a plane stooli having; two handles by means of which it can bemaanallyoperated. The plane stock has a cutter which can be. projectedfrom the. sole of the stock nnd which is mmovably mounted. so that it,an be replaced by other cutters of different sizes. The cutter can besecured in a plurality of positions and 5 provided with a gage to insurethe maintaining of the cull-or at a uniform degree of projectionfrom the stock. One of the handles of the plane is rigid. while theother is revolublo and is connected by means of a suitable intermediategear with the cutter, in such a way that by llltll' ing the movablehandle in one direction or the other the cutter is projected from orwillnlrawn toward the stock.

Referring more particularly to the drawions, 5 represents the stock ofthe plane, which comprises preferably flat: plate or sole of anysuitable torn]. Near the center, adjacent to the rear edge. the stock 1has a. euttenpost 2 provided with a. suhaantiully 7'0 \Ol'tiCzilguide-opening 3. in Whirl! is slidalily mounted the .hanl l.- of thecutter, The shank l, at the lower end hos a law; all disposal cutterblade 5 and in torn-ml ill. one. side -with a rank (3. in a suitable.recess T uithin the post :3, i z hunted a pinion S in nu-r-rh with therack (i and rigidly mounted upon the shaft 9, extending through a suitable transverse opening IQ of the post. :17 U:1l1a ped yoke ll is2\l.'1';l]l1lt l'\\li,li i s side 56 adjacent to the sides of the postand extendinntoward the shaft 9. A. threaded pin it? in loeated in asuitable threaded opening of the post, and has a heart 13 by means 01which it can be manually operated and adjacent to which it carries theyoke ll. The pin 12 has an annular groove 14.. which is engagerl by theextremity of a stud 15 mounted in a threaded opening of the yoke. andholdfor, the pin 12 in position with respect to the yoke.

Thus, as the pin 12 i5 turned in one direction or the other by means ofthe head 13, the yohe is advanced toward or moved away from the shaft5.). Py Forcing the sides:

of the yoke, which lire slightly rec-eased For 9 the purpose, firmlyagainst the shaft, the latter can be held against rotary moven'ient andthereby the cutter which rontrolled by theshaft can be locked in aplurality of positilnis. A ,eollar 1(3, constituting a. gage; lot ismounted upon the portion of the shank 4 which projects above the post,and. has a ;et:- screw 17 by means of which it can be rigidly secured tothe shank.

At one side, the plane stock has an annular 10 handle. support 18,rigidly mounted in position thereupon .and carrying a handle 19, held inposition by FL screw stem 20, extend ing upwardly from the handleSupport. and

)resenting a threaded extremity The 11" handle 19 is hold in positionupon the felt-n1 20 by m ans ot' a oonnlnrsunk nut 22,

mounted upon the threaded extremity 21 and arranged in a suitable recessat the top of the handle. At the opposite side of the plane stock asecond handle support, 23 is mounted in position by means of screws 24,extending upward through suitable openings in the sole plate. The handlesupport 23 has a substantially central. projection 25, upon which isrevolubly mounted a bevel gear 26, having an integral laterallydisposedand flared socket 27, in which is carried a handle 28. A stem 29is located in a suitable opening extending through the handle support23, and the projection 25, and has a head 30 counter-sunk in a recess atthe upper end of the handle 28, the stem 29 extending through alongitudinal openin in the latter. The re cess which holds the ead 30 islined with a suitable sleeve 31. At one side the handle support 23 has arecess 32, in which is arran ed a bevel gear 33 in mesh with the bev lgear 26 and rigidly mounted upon the shaft 9 which extends toward thehandle support 23. The stock of the plane has an extension 3%, adjacentto the handle support 23, which serves as a bearing for the shaft 9 andas a stop or thrust block for thebevel gear 33, the back of whichengages the extension 34. The stem 29 has a longitudinal groove 35 whichis engaged by a set-screw 36 carried b l the handle support 23. Theset-screw holds the stem 29 against rotary movement. The handle 28 whichis arranged to be turned about the stem, seats upon the projection 25 ofthe handle support.

To adjust the cutter of the plane, the head 13 is turned to release theyoke from the shaft 9, and the handle 28 is then turned in one directionor the other until the cutter blade is projected the desired distancefrom the sole plate. It will be understood that as the handle 28 isturned the shaft 9 is turned by means of the bevel gears 26 and 33, andin consequence, the cutter is raised or lowered by the operative enagementof the pinion 8 with the rack 6 ormed u on the cutter shank 4.When the blade as been suitably adjusted, the head 13 is up erated tojam the yoke against the shaft to lock the latter imposition. Theset-screw 17 is then loosened and the gage-collar 16 slipped down theshank 4 until it engages the top of the post. The set-screw 17 is thentightened and the collar thereby secured in position upon the shank.Should the cutter slip this would then no longer rest in positionengaging the top of the post. provide a central opening 37 in the stockor sole plate, substantially above the cutter blade, to allow theoperator to see the opera- {ion of the tool and through which opening hewaste wood finds exit. As shown in Fig. 1, the cutter blade 5 can beseen through the a ening 37, cutting the groove 36 in a plank By meansof the handle the cutter blade can be adjusted while the plane is beingused, and even after the yoke has been tightened somewhat, for theconstruction of the regulating mechanism permits the application ofconsiderable force to the adjustment of the blade.
